Description of Photograph

Digital copy of a photograph of an unfilled rack on LEO I, with the engineering console in the background.

This image appears in the interactive plan for our Virtual LEO I installation, p74.


Research comments: The almost empty carcass shown in this photograph gives an insight into how the racks were constructed to house LEO I's thousands of valves. The engineer's console in the background changes considerably over time, as the pioneers establish what they need to be able to monitor while the calculator is running. Under the console an oscilloscope sits on the floor; these scopes were a vital piece of equipment for the engineers. (LM)
